    Yes, I did try the 9-volt battery test as directed by tech support, they are the ones that told me the carriage needs to be replaced. when I did the test the carriage moved, even when I ran voltage through the wires it still moved. after this tech support told me that the carriage needed to be replaced. How do I locate the Z Chip?

    If you see the motherboard, look for a black heat sink if you take it out you will see 4 of them… to test them… do either freeze test or get a thermal gun much easier or spot temp gun. You will need to de solder then buy new IC very cheap like $8-10$ for 10 pieces solder it to the bad then you will have a working one again

    I have the MH 871 MK2 I just replaced the carriage per tech supports recommendation because the carriage was not moving up and down when cutting. after the successful replacement of the carriage, I am still having the same issue. does anyone have any other recommendations besides getting rid of this cutter and getting a better one?

    You probably have a bad motherboard… based on my experience 1 of the 4 ICs overheated and bought 10 ICs from China about $8 then soldered it to the board and it’s working now
